Honestly, as I have said before... we might as well just sit and wait it out for the announcements (or maze facades) to actually know what the legit line-up is.. I'm taking everything with a huge grain of salt this year. I'd suggest doing the same until announcements start rolling in.
"IF" we have indeed lost IPs, this is exactly why the event needs to use the crap they own (which doesn't mean 6 years in a row... *ahem* Purge) or do what the other successful haunt events do, including Orlando... do something non-IP original. Of course "IF" Murdy and team had been smart (which will never happen), if an IP is lost, you do what Orlando did back in the day before they really started IPs... you make an original maze that is loosely inspired by a particular movie/tv show (Demon Cantina = From Dusk Till Dawn, Body Collectors = Silent episode of Buffy the Vampire Slayer, Interstellar Terror = Event Horizon, etc etc)
